Sarah,

Great post and I am a favor of Google authorship, however it has just presented my sites with a problem, upon updating the Jetpack today I noticed I now have two author sections. One from Jetpack and one from the author plugin I was already using.

After many attempts to disable the functionality of Google+ in Jetpack, to which I was unable to clear the author box, I decided I would have to remove the author plugin I had. (which is nicer and had more functionality.

To boot, I keep some blogs, such as niche blogs separate from my normal Google+ profile. It is nice of Jetpack to provide the functionality, I would like the decision of using it up to me.
